TO295J

1.5 µm DFB chip in TO can for Uncooled applications

Overview

The Broadcom TO295J is an hermetic sealed TO can device with integral photo diode for optical output monitoring using 1550nm single mode edge-emitting laser diode chip for use in uncooled applications up to 2.7Gb/sec. The laser is mounted into a TO-56 header and hermetic sealed with a specific lens cap. The laser design is a capped mesa buried hetero-structure (CMBH) grown on n-type substrate with multi-quantum well (MQW) active layers and distributed-feedback (DFB) grating layer. The facets are coated with an anti-reflectance layer on the front facet and a high reflectance coating on the rear facet.
